Stack up a beautiful rainbow tower in the reaction game rainbow stacker. stop the sliding plates at the right moment to stack one on top of the other as neatly as you can. if your timing is perfect, the blocks will slot together and remain the same size. however, if your timing is a little off, there'll be some overhang. any overhang is chopped off, reducing the size of the next platform. this way, your tower will shrink with every moment of imprecision. keep going until the last, tiniest sliver misses the mark. how far will you get?
